For hundreds of years, explorers have searched for secret passageways and concealed rooms inside the Great Pyramid of Giza, in Egypt. Now, a robot is finding what no explorer could the robot, called Djedi. What is Djedi? It is a part of a project led by an international team of researchers.

The Great Pyramid of Giza

It is the largest of Egypt's 70 pyramids. When it was built around 2550 B.C., it was about 480 feet high.

One of the pyramid’s mysteries is what lies in the passageways beyond two eight-inch-square shafts. Because the narrow tunnels climb so high – they are equal to a 13-story building – only a robot can explore the entire length of the tunnel.

In 1993, a different robot reached at the end of one of the passageways. Bur when it drilled through a wall, its camera revealed another wall. Djedi’s advance tools give it greater access, allowing it to explore further.

New Clues to Decode

Djedi the Pyramid Explorer

One of the new robot’s features is a snakelike camera, able to fit through small spaces and bend around corners. When Djedi got to the end of passageway, it pushed its camera through a hole and peeked around the corner. There, if found red hieroglyphs and lines in the stone. The markings were last seen when pyramid was built, more than 4,500 years ago.

Researchers believe that if the hieroglyphs can be deciphered, they may explain why the tunnels were built. The Djedi robot, it has been exploring the Great Pyramid. The robot found the red markings inside the pyramids. What do they mean? What other secrets are hiding beyond a long shaft or behind a stone door? Perhaps a small robot will reveal the answers.
